16 bit greyscale tiff to pseudocolor

Hello,

I have 16 bit greyscale TIFF images (actually 12 bits of
information
into a 16 bit file) obtained from a CCD camera.
I would like to map this onto a red-blue
"pseudocolour" gradient, e.g.
in 24 bit rgb png, as my monitor only handles 8 bits of
greyscale and I
would like to see the full dynamic range (as opposed to just
dumping 4
bits).
I have been playing around with the -map option and
generated gradients,
but I can't figure it out.

Any ideas on how to do this?

Thank you very much,

Klaas

You don't use a -map, but a color index color lookup table.
